Local context
Working in Crown Mines
We service Crown Industrial Park and the surrounding blocks of Crown Mines, Johannesburg, with access off the M1 and N1. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.

FAQ
Bock refrigerant leak detection in Crown Mines
How fast can a technician service Bock equipment at a seafood processing & fisheries site in Crown Mines?
Crown Mines sits on the M1 and N1, so our Johannesburg dispatch reaches most Crown Industrial Park sites inside a standard callout window. Emergency refrigerant leak detection runs 24/7 because slow freezing forms large ice crystals and ruins texture.
Do you stock OEM components for Bock systems?
Yes — Bock shaft seals, suction filters and gasket kits. Bock (Germany) equipment on R404A/R717/R744 charges is supported with the fast-moving spares held at our Pretoria North workshop and non-stock items brought in on OEM order.
What pressure testing and gas compliance certificates are provided?
Every refrigerant leak detection job closes with a pressure test record and gas handling Certificate of Conformance issued under SANS 10147 by a SAQCC Gas registered technician, plus the HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Seafood Processing & Fisheries run at −40 °C blast to −25 °C hold at 85–95% RH, with refrigerant leak detection performed against System-dependent, tested to design pressure. Slow freezing forms large ice crystals and ruins texture
